Specifications

Description The California Analytical Instruments’ 700 Series HFID Analyzer is designed to continuously measure the total concentration of hydrocarbons within a gaseous sample. The analyzer exhibits superior sensitivity and response time.

The 700 Series Hydrocarbon Analyzer utilizes the principle of Flame Ionization Detection (FID) to determine the total hydrocarbons within a gaseous sample. The HFID analyzer has a heated oven (191oC) which contains a burner and an optional heated pump. The small flame of the burner is elevated and sustained by the regulated flows of air and either pure hydrogen or a 40/60 mixture of hydrogen and (helium or nitrogen). The split ring

detector contains 2 electrodes. One electrode is negatively polarized using a precision power sup-ply and the other electrode, known as the “collec-tor” is connected to a high impedance, low noise electronic amplifier. The two electrodes establish an electrostatic field. When a gaseous sample is introduced to the burner, it is ionized in the flame and the electrostatic field causes the charged particles (ions) to migrate to their respective electrodes. The migration creates a small current between the electrodes. This current is measured by the precision electrometer amplifier and is directly proportional to the hydrocarbon concentra-tion of the sample.
